Web Development for UK Startups, SaaS, and Agencies
MicroPyramid is a 14-year-old senior-led team that builds custom web applications for UK businesses. We cover frontend, backend, and hosting in the same engagement — SaaS platforms, customer portals, progressive web apps, and rebuilds — with live overlap during UK working hours, GBP billing via Stripe or GoCardless, and UK GDPR-aware delivery from the start.
The UK web market is demanding: ICO obligations, WCAG 2.2 accessibility expectations from public-sector and enterprise buyers, and data residency requirements from procurement teams. We have worked directly with UK organisations — including Bough Digital — and understand what it takes to ship web applications that UK users and buyers will trust.
Why UK Teams Choose Us for Web Development
Four reasons UK founders and product teams pick MicroPyramid over a local agency or a generic offshore team
Morning Standups During UK Hours
We maintain approximately 4.5 hours of daily overlap with UK working hours. Your team gets live standups, same-day decisions, and pull-request reviews before your afternoon — not responses you wake up to the next morning.
UK GDPR, ICO & WCAG 2.2 Aware
We build with the UK GDPR and the Data Protection Act 2018 in mind (regulator: the ICO), and with WCAG 2.2 accessibility baked into frontend work — the standard UK public-sector and enterprise buyers expect. AWS eu-west-2 (London) available for UK data residency.
GBP Billing via Stripe or GoCardless
Invoices in GBP, collected via Stripe or GoCardless Direct Debit. No currency conversion headaches, no wire-transfer friction. Billing that fits how UK businesses actually operate.
Senior Ownership, Not a Ticket Mill
Founders and senior engineers directly own every web engagement. You will not be passed to a delivery layer of junior developers. The person you talk to in discovery is the person building your application.
Web Development Services for UK Businesses
Six services covering the full web stack — from UK-focused web apps and APIs to accessible frontends and London-hosted deployment
Custom Web Applications
Bespoke web applications built around the exact workflows your UK business runs on — customer portals, internal tools, booking systems, and SaaS platforms. No off-the-shelf compromises, no plugin sprawl.
- SaaS platforms and dashboards
- Customer and client portals
- Internal and admin tooling
Frontend Development
Fast, accessible frontends in React and SvelteKit, built with WCAG 2.2 accessibility in mind — important for UK public-sector and enterprise buyers. Clean, trustworthy interfaces that UK fintech and proptech users expect.
- React and SvelteKit builds
- WCAG 2.2 accessibility awareness
- Responsive, mobile-first UX
Backend & API Development
Reliable backend systems and APIs using Django, Python, and FastAPI, hosted on AWS eu-west-2 (London) when UK data residency matters. REST and GraphQL endpoints built for real integration loads.
- REST and GraphQL APIs
- Third-party and payment integrations
- Data modelling with UK GDPR in mind
Progressive Web Apps
App-like web experiences that load instantly, work offline, and run across every device — no app-store gatekeeping. Ideal for UK SaaS and ecommerce teams who want reach without two native codebases.
- Offline support and caching
- Installable, app-like experience
- Push notifications and fast loads
Security & Performance
Enterprise-grade security and performance work — audits, hardening, and Core Web Vitals tuning. Built for UK organisations that answer to the ICO and to enterprise procurement reviews.
- Security audits and hardening
- Performance and Core Web Vitals tuning
- Load testing and monitoring
Cloud Deployment & Hosting
Deployment and managed hosting on AWS eu-west-2 (London) with automated CI/CD pipelines. UK data residency, predictable scaling, and infrastructure that does not wake you at 3am.
- AWS eu-west-2 (London) hosting
- Docker and automated CI/CD
- Auto-scaling and observability
UK Teams We Build Web Apps For
If any of these situations match where your UK team is right now, we should talk
UK Startups Launching a Web Product
You need a first web application built fast and built well — without the overhead and cost of a full London engineering hire to get to launch.
UK SaaS Companies Scaling the App
Your web platform has traction in fintech, proptech, or agency software and you need extra delivery capacity for new features, dashboards, and portals without growing headcount.
UK Businesses Replacing a Legacy Site
Your current site or web app is slow, unmaintainable, or failing accessibility checks. You need a senior team to rebuild it properly with WCAG 2.2 and UK GDPR in mind.
Agencies With Complex Client Builds
UK digital agencies that have committed to ambitious web projects for clients need a reliable engineering partner to own full-stack delivery end-to-end — Bough Digital is a real example.
Ecommerce & Proptech Teams Going Custom
You have outgrown templated platforms and need a bespoke, performant web application with custom integrations, checkout flows, and search built for your UK market.
Teams With Limited Engineering Bandwidth
Your in-house engineers are at capacity. You need a senior external partner who can own web delivery with morning standups during UK working hours — not a ticket-mill you have to manage.
Best Fit For
- UK fintech, proptech, SaaS, ecommerce, and agency teams building real web applications
- startups and SMBs that need frontend, backend, and hosting to move together
- rebuilds where UK GDPR-aware architecture and WCAG 2.2 accessibility matter from day one
- projects that need a senior external partner to own delivery — not just a list of tickets
Not the Right Fit When
- a quick brochure site that an off-the-shelf template or page builder would cover
- engagements looking only for staff augmentation without delivery ownership
- projects blocked mainly by legacy rescue or migration risk rather than new web delivery
- teams adding AI as a slogan rather than a concrete feature inside the web product
If the next step is an AI workflow inside the app, see AI Feature Development. Rescuing a legacy codebase? See Modernization & Migration.
Public proof for UK teams: Bough Digital is a UK client we built a custom agency web platform for, and Refactored.ai shows complex full-stack web delivery at scale.
